Books are the main tools used by human beings to record all their achievements, and also the important media for human beings to blend their feelings, acquire knowledge and inherit their experiences, which has made great contributions to the development of human civilization. Therefore, regardless of ancient and modern times, people always give the highest affirmation and special care to books. Hand-refined paper is especially suitable for China's calligraphy and painting, which can be divided into two kinds: raw and cooked.

Many great creations of mankind, mostly through the long years of development process, have gathered the painstaking efforts of countless people, and they have always grown and developed, and books are no exception. Take China as an example, it has a history of at least 3,500 years, during which people have invested more wisdom and labor. Books have been repeatedly created and improved, which makes them what they are today. Generally speaking, in history, except some books made for special purposes, the development of books can be found in a little context. In the earliest communication, people may only use gestures or volume as a medium when gesturing to each other. Later, from the accumulation of experience, some fixed syllables were determined to represent a certain meaning, so human beings walked out of the silent era and entered a society with words and no words.

With language, human beings often remember what they hear by memory and then repeat it to others; Or spread your ideals and personal experiences through language. This purpose and method are similar to the functions of future books, so it can be called oral living books. People's memory is limited in the end, and sometimes it will go out of shape. Spoken movable type books are bound to have many defects. Clever humans have invented many ways to help memory, the most representative of which is knotting. We can call it a rope book, which expresses different meanings through the size, tightness, quantity and different colors of knots.

Rope books can be spread far away and preserved for a long time, which has some advantages over language. However, due to the limited change of its style, it can not meet the needs of the rapidly progressing human society. Therefore, human beings began to imitate nature, simplify the external image, transform it into a simple image, and then improve it again as a symbol of the image. This kind of picture, that is, the embryonic form of existing characters, is generally called character painting. Later, after further improvement and evolution, it gradually became a stereotyped hieroglyph. After a long period of development, countless fonts have finally been achieved for people to apply. The appearance of characters not only opened up a new realm for human civilization, but also laid a solid foundation for books.
